According to the World Health Organization (WHO), life expectancy and medical advances has lengthened lifespans in most countries, and the number of people aged 60 years and older has doubled since 1980. Living longer is easy, with the advances we’re making in the domain of science and medicine. But we’re probably more interested in answering the question of how we can age successfully. That and avoiding dementia.
On this International Day of Older Persons, let’s review what’s been known for a while:
1. Eat your veggies!
There’s no getting away from it. Studies show that those who live a long independent life in Okinawa eat lots of fruits and vegetables, as well as fish and whole-grains. Their habit of eating until they feel 80% full is also likely a major contributor to the reason for their disability-free longevity.
2. Stay active!
Research indicates that cardiovascular disease risk is a major contributor to Alzheimer’s and vascular dementia (Fratiglioni et al., 2004). Lowering this risk through regular, weekly moderate-to-vigorous exercise is one strategy. And also a reason why Sardinians, who herd sheep over steep hills, are reputed to age successfully (see this TED video about the blue zones).
3. Engage your social brain!
A review of the literature shows that adults who are socially active are also likely to have better psychological wellbeing in their later years; being engaged in social activities and having stronger social networks is a protective factor against dementia (Fratiglioni et al., 2004). Various studies show that religious attendance, community involvement, and being employed are associated with better mental wellbeing among older adults. These activities are also shown to be helpful for local residents too…
So to sum, it’s the same thing that us active younger (a little bit younger) adults need to start doing. But we just need to keep doing them!
